A couple of days ago, a car following me in the right lane tried to get between me and the streetcar in the center lane. Frustrated (they didn't remotely have enough room) they followed me to the stop line (the light was red) and honked.
The simple controls of a car can express a surprising amount of information. In this case, a honk told me I had an entitled driver behind me. and that if I moved to the side they would try to fit their 2.5-3 metre wide car, my bike which takes up at least a metre, the metre they have to leave between my bike and their passing car, and the half metre clearance required between the streetcar and their car into the four metres between the streetcar and the curb. In other words, I knew if I didn't ride in the center of the lane I could expect a dangerous close pass.
The time has long come and gone for motor vehicle operators to realize ordinary drivers of non-emergency motorized vehicles don't have priority over other road users, and increasing numbers of cyclists will not compromise our safety for your impatience. You impatience won't kill you or us; getting sideswiped by a poorly-judged pass from an impatient and entitles motor vehicle operator very well might.
Cyclists are here and we will not go away, so if you plan to drive, get used to us.
